Plaque, a sticky film of bacteria, constantly forms on the surface of your teeth. When you consume sugary foods or drinks, the bacteria in plaque will produce acids. These acids will attack your tooth enamel. The stickiness of plaque keeps these acids in close contact with your teeth, ultimately destroying your tooth enamel. This is when cavities can form.
If plaque stays on your teeth, it hardens into tartar, which can cause gingivitis, the mildest form of gum disease.
When sugars are added to foods to sweeten them, they add calories but don’t add any nutritional value. They are known as added sugars, unlike the naturally occurring sugars that exist in fruits and milk. Foods like candy, cookies, cakes, and muffins not only offer no nutritional value, the high amount of sugar they contain can adhere to your teeth, resulting in tooth decay. Sugar-containing drinks, including sodas, juice, sweetened coffee, or tea, are also very harmful because they provide a constant sugar bath for your teeth.
You might wonder if all types of added sugars cause tooth decay. For instance, you might be curious if dextrose (a type of sugar that comes from corn) is bad for your teeth. The answer is yes. While refined sugar found in candy or sweetened cereals is typically the most harmful, all added sugars can create plaque and cause tooth decay. This is especially the case when they’re consumed in excess.
Sugar can be hard to avoid, but paying close attention to what foods you’re buying and eating can help you stay away from tooth decay. Avoid added sugars and instead, have some raspberries for dessert. And of course, maintaining good oral hygiene will leave you with a healthy mouth for many years to come.
